Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors and interactive decorations fail to properly scale and adjust images based on the size, shape, and depth of the space they are displayed in, leading to distortion and warping when viewed from different angles.
Innovation Solution
A computer-implemented method using an electronic device with image sensing, processing, and projecting components to capture images of the environment, generate a depth map, select images, and alter them based on the depth map to ensure correct scaling and projection on various surfaces within the space, minimizing distortion and warping.

Engineering Contradiction Analysis
1Adaptability or versatility
If images are projected on surfaces in spaces with depth or multiple objects, then the projection covers more complex environments, but the images become distorted and warped due to incorrect scaling
Solution Approach 1:
The system performs preliminary depth mapping of the projection environment before displaying images. The processor captures depth information about surfaces and objects in the space, then uses this pre-acquired data to pre-distort or pre-scale the images so that they appear correct when projected onto the complex surfaces, thereby resolving the distortion problem in deep or cluttered spaces
Solution Approach 2:
The system uses depth sensing to continuously monitor the projection environment and feeds this information back to the processor, which adjusts the image scaling and distortion parameters in real-time based on the detected spatial characteristics, ensuring accurate projection despite environmental complexity
2Manufacturing precision
If depth mapping and image alteration processing are added to correct distortion, then image accuracy improves, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single projector unit: the projector includes both image projection capability and depth mapping capability, allowing one device to perform both environmental sensing and image display functions, thereby reducing overall system complexity while maintaining high projection accuracy
Solution Approach 2:
The projector performs its own environmental assessment and self-adjustment by using its integrated depth mapping sensor to detect the projection surface characteristics and automatically altering its output images accordingly, eliminating the need for external measurement devices or manual calibration
